IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Patent No. 115,106, dated May 23, 1871.

T all whom it may concern:

Be it known that I, EI'GENE ROCK, of Greenvale, in the county of Queens and State of New Ycikhave invented a. new and useful Improvement in Cotton and Hay Presses; and 1 do hereby declare that the tiillowing is a. lull, clear, and exact description thereof, which will enable others skilled in lheart to make and use the same, reference being bad to the accompanying drawing forming part of this specification.

My invention consists in a new way of combining mechanical parts to form an improved opt ra tive mechanism for actuating the follower of a hay or cotton press, as hereinafter fully described, and subsequently pointed out in the claim.

In the accomparying drawing, Figure 1 represents a vertical s ction through the press taken on the line 00 a: of Fig. 2. Fig. 2 is an end view of the press IJUlilJg from the line 3 3 of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is the frame. B, pressing'ohamber. O is the follower. D is the follower-bar. E I) are vertical ratchets on each end of the press. "he press-box is slotted .between the ratchets, as seen at F, to allow the follower-bar 1) to descend. G represents a lever at each end of the press, upon the top of the short end of which is a plate, 11, having at its extreme end projecting gudgeons I I, which gudgeons engage with the ratchet-teeth. The lever is connected with the tbllower-bar by means of the hook J, link K, and eye L, the latter being firmly attached to the bar. M is a holdingpawl at each end of the bar, made in the form of a T, the top of which engages with the ratchet-teeth, as seen in Fig. .2.

It will be, seen from this arrangement that when the le ers are. worked together down the ratchets the bar and follower will be drawn down onto the coutents'of the press with great force. What the levers gain is held by the pawls. 'lhe gudgeons l 1 form the fulcrumpIns of the levers, and it will be seen that a powerlul purchase is obtained upon the follower-bar. The pawls M M are. placed loosely in the recesses N N, through the plates 0 U, and drop by their own gravity, so as to engage with the teeth as they descend. \Vheu the cotton or contents of the press have been sutticiently condensed the pawls are removed and the levers are detached from the links, which allows the follower-bar to be drawn from the :1 )l'.

I do not confine myself to any particular 4 style of press, but require the slots therein. My invention is in the mode of forcing down the tcllower.

Having thus described my invention, I claim as new and desire to secure by Letters {atent- 'lhe,arrangement of the T-shaped pawls M, i
